摘　　要：以抗生素磺胺甲恶唑(SMZ)为目标污染物,研究SO_4^(2-)、Cl^-、NO_3^-、NO_2^-、PO3-4、NH4和Ca2+等不同离子及其含量对铁铜双金属微电解处理SMZ的影响。结果表明,SO_4^(2-)对SMZ去除率没有明显影响,低含量Cl-、高含量NO_3^-、NO_2^-和NH+4能提高SMZ去除率,但高含量Cl-和低含量NO3-4、PO3-4和Ca2+会抑制SMZ去除。The antibiotic sulfamethoxazole（SMZ）was chosen as the target pollutantsand the effect of different ions such as SO42-, Cl-, NO3, NO2-, PO42-, NH4＋ and Ca2＋ and their concentrations on the degradation of SMZ during Iron-copper double metal micro electrolysis process was investigated. It was found that SO42 had no significant effect on SMZ removal rate, and low content of CI, high content of NO3-, NO2- and NH4＋ could improve the removal rate of SMZ. However the SMZ removal efficiency was inhibited by high content of Cl-, low content of NO3-, PO43- and Ca2＋.
